HDMI registers channel map controls per PCM. As PCMs are not registered during dai_link init callback, store the pcm ids and codec DAIs during this init callback.
Register for late probe and call the jack_init API which also registers channel map in the late probe callback handler.
The patch following the machine driver changes adds the channel map control in the hdac_hdmi codec driver.
